To all 'whom t may concern:

Be it known that 1, Jol-IN WILLMAN WAL- vATNn, a citizen of the UnitedStates, residing at Sherman, in the county of Minnehaha, State of SouthDakota, have invented certain new and useful Improvements in Liquid-FuelBurners; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in burners and particularly toburners for burning kerosene or like oils.

The principal object of the present invention is to provide a device ofthis character which can be readily used in the fire-pot of a cookstove, especially in warm weather when it is not convenient or desirableto build a wood or coal lire.

Another object is to provide a device of this character which is simplein construc- 'tion', safe and easy in its operation, and

which will give great heat while permitting the lids of the stove top tobe within the holes in the usual manner.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of my improved oil burner.

Fig. 2 is a top plan view of the same.

Fig. 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a transverse sectional view taken on the line-4 4 of Fig. 2.

Referring particularly to the accompanying drawing, 10 represents a baseon the ends of which are mounted the vertical uprights 11. Extendingbetween these uprights and supported at its ends thereby, is

a horizontal tubular chamber 12, the ends being provided with theremovable screw plugs 13 and 14 respectively. The former of these plugs,13, is formed with a central longitudinal opening 15 in which is securedone end of the hollow oil conveying wire 16, while the other end plug14, is solid to prevent escape of oil through that end of the tube. Onthe base 10 is formed the pan 17, and in this pan is disposed a sheet ofasbestos 18 which is adapted to be soaked in the oil and ignited for thepurpose of heating the tube 12, as will appear more fully hereinafter.

Disposed longitudinally within the tubular chamber, and concentrictherewith, is a solid metal bar 19 having the supporting legs 20, saidbar being adapted toprovide additional heat radiating surface tovaporize the oil which flows into the chamber 12 through the wire 16. Ahollow plug 21 is secured in the upper side of the tube 12 and has anexternally threaded nipple 22 on the side thereof for the detachableconnection ofa pipe 23 which is adapted to receive the gas generated inthe tubular chamber 12. rEhe pipe 23 extends laterally from the plug 21and thence downwardly, the lower end being turned upwardly in adirection toward the central portion of the lower side of the chamber12, and from this end of the pipe 23, as shown at 24, the oil which isvaporized, issues and is burned. The flame from the tip of the burnerwill strike the lower side of the chamber whereby said chamber will beproperly heated and the oil which flows thereinto will be vaporized. Theother end of the wire 16 is connected to a pressure tank 25, containingthe oil which is forced through the wire 16, into the chamber 12, andthence, in the form of gas, from the tip of the pipe 23.

rlhe device is particularly adapted for use in connection with a cookstove, wherein it is not desirable to build a wood or coal lire,especially in the warmer weather, the burner and supporting parts beingplaced within the fire-pot of the stove, and on the grate. The lids ofthe stove may then be replaced within the holes, a notch, not shown,being necessary in one edge of one of the lids, t0 permit the passage ofthe wire 16 therethrough. rllhe tank may be placed at any safe pointadjacent the stove, while in operation.

From the above it will readily be seen that the devicecis extremelysimple in construction, effective in operation, and can be manufacturedat a comparatively low cost.

What is claimed is:

The combination with a pressure supply of liquid fuel, of a burnerincluding a panshaped base, uprights at the ends of the base,

a horizontal Vaporizing chamber supported Veying means between the saidsupply and by the uprghts, a longitudinal heat retainone end of the saidchamber.
